What makes carbon such a special atom?
Atoms are like letters because they stand for something (not a sound, but an element though)
molecules are clusters of atoms
water can be separated into h2 and 02 with electrolysis and the h2 explodes and the 02 makes a smoldering flame burn again
water would be more dense (heavier) if all the atoms were stuck together closely and the weight of a single molecule of water is known
the number of protons, neutrons and electrons make atoms different
by smashing them and seeing what comes out
by accelerating them in a ring to almost the speed of light and them letting them hit each other with magnetic fields
antimatter?
carbon is the atom all life on earth is based on. all the molecules of your body are based on it.
they know that h2o is water because water has 2 parts Hydrogen (H2) and 1 part oxygen (0) so that makes H20
Each molecule is made up of atoms and in a water molecule to every atom of oxygen there is 2 hydrogen Atoms
